(9%) Problem 1: Consider a conducting rod of length 32 cm moving along a pair of rails, and a magnetic field pointing perpendicular to the plane of the rails At what speed (in m/s) must the sliding rod move to produce an emf of 0"95 V in a 1.3 T field?

Explanation / Answer

here,

length of rod , l = 32 cm = 0.32 m

magnetic feild , B = 1.3 T

let the speed of sliding rod be v

the EMF produced , V = B * v *L

0.95 = 1.3 * v * 0.32

solving for v

v = 2.28 m/s

the speed of the sliding rod is 2.28 m/s
